“…Many factors contribute to this problem, including a lack of education on the part of the public and poor recognition of trematode infections by public health authorities (Dixon and Flohr 1997). Furthermore, there are indications that infections have been increasing in the last few years because of an increasing production of fish and shellfish in unhygienic fish ponds, and the popularity of raw, undercooked, or insufficiently processed food in many parts of the world (Abdussalam et al 1995). Additionally, with increased international travel, food-borne trematodiases are important to understand, diagnose, and treat, particularly in areas where infection is common (Slifko et al 2000).…”

“…Current estimates indicate that 40-50 million people world-wide are infected with food-borne trematodes (Abdussalam et al 1995;Lima dos Santos 1995). These infections are endemic in various parts of the world, particularly Southeast Asia (Dixon and Flohr 1997).…”

“…These infections are endemic in various parts of the world, particularly Southeast Asia (Dixon and Flohr 1997). More than 10% of the world population is potentially at risk of food-borne trematode infection (Abdussalam et al 1995). Many factors contribute to this problem, including a lack of education on the part of the public and poor recognition of trematode infections by public health authorities (Dixon and Flohr 1997).…”

Food-borne trematodiases still remain a public health problem world-wide, despite changes in eating habits, alterations in social and agricultural practices, health education, industrialization, environmental alteration, and broad-spectrum anthelmintics. Food-borne trematodiases usually occur focally, are still persistently endemic in some parts of the world, and are most prevalent in remote rural places among school-age children, low-wage earners, and women of child-bearing age. Intestinal fluke diseases are aggravated by socio-economic factors such as poverty, malnutrition, an explosively growing free-food market, a lack of sufficient food inspection and sanitation, other helminthiases, and declining economic conditions. Control programs implemented for food-borne zoonoses and sustained in endemic areas are not fully successful for intestinal food-borne trematodiases because of centuries-old traditions of eating raw or insufficiently cooked food, widespread zoonotic reservoirs, promiscuous defecation, and the use of "night soil" (human excrement collected from latrines) as fertilizer. This review examines food-borne intestinal trematodiases associated with species in families of the Digenea: Brachylaimidae, Diplostomidae, Echinostomatidae, Fasciolidae, Gastrodiscidae, Gymnophallidae, Heterophyidae, Lecithodendriidae, Microphallidae, Nanophyetidae, Paramphistomatidae, Plagiorchiidae, and Strigeidae. Because most of the implicated species are in the Echinostomatidae and Heterophyidae, emphasis in the review is placed on species in these families.

“…The infective stage of these parasites (metacercariae), are found in the edible tissues of freshwater fish or fish found in unhygienic water bodies (Abdussalam et al, 1995). These parasites are resistant to heating, freezing and salting (Abdussalam et al, 1995). Human infection with food borne trematodes may result from the ingestion of raw or inadequately processed food such as contaminated fish.…”

“…Fish obtained from the water could harbor parasites of some trematode species that are known to cause gastrointestinal diseases in humans when ingested (Arvanitidou et al, 2005). The infective stage of these parasites (metacercariae), are found in the edible tissues of freshwater fish or fish found in unhygienic water bodies (Abdussalam et al, 1995). These parasites are resistant to heating, freezing and salting (Abdussalam et al, 1995).…”

Life on earth depends on water. However, there is scarcity of portable water supplies in South Africa especially in rural areas. This results to the consumption of untreated water that may be contaminated with microbial species such as Klebsiella. The aim of the study was to investigate Klebsiella contamination levels in water from the Modimola dam situated adjacent the Modimola village, in the North West Province, Mafikeng -South Africa. Nine water samples (three each) were collected from the upstream, middle-stream and down-stream of the dam. The samples were analyzed by plating on mFC and Eosin methylene blue agar plates. The blue isolates on mFC were counted and results recorded. The identities of metallic sheen colonies on EMBA were determined using Gram staining, preliminary (TSI and oxidase test) and confirmatory (API 20E, gapA specific PCR) tests. A total of 504 presumptive isolates were screened and 28 (35.9%) Klebsiella species were positively identified. Despite the fact that faecal coliform bacteria were not detected in tap water, the level of faecal contamination was higher in samples obtained from the upstream than the middle stream and; than the downstream. All water samples collected from the different sites of the Setumo dam contained Klebsiella species and this indicates the risk that water from this dam can pose threat to the inhabitants of the Modimola community who use the water for fishing and some daily activities.
